Apparatus Utilizing electromagnetic Induction based on Reaction upon External Force for Providing Passive Haptic Feedback, Module Providing Passive Haptic Feedback Using the Same, Portable Unit Using the Same and Control Method therewith
PURPOSE: An apparatus utilizing electromagnetic Induction based on reaction upon external force for providing a passive haptic feedback, a module providing passive haptic feedback using the same, a portable unit using the same and a control method therewith are provided to supply to a user a haptic feedback corresponding to measured external force by measuring the strength of external force through an electric signal within a second magnetic generating unit. CONSTITUTION: A first magnetism generating unit(30) is connected to a lower portion of a pressure plate(20), and generates magnetic force. An elastic force supply unit(40) provides the pressure plate with elastic force. A second magnetism generating unit(50) generates an electric signal through an electromagnetic induction effect of the first magnetic generating unit, and generates magnetic force. A measurement unit measures the strength of the external force through the generated electric signal.
